Molecular Genetics
Kobayashi et al. (2000) reported that a heterozygous premature termination codon mutation (604011.0001) in the UNC119 gene resulted in late-onset cone-rod dystrophy. In transgenic mice carrying the same mutation, they found age-dependent fundus lesions with accompanying electroretinographic (ERG) changes consistent with defects in photoreceptor synaptic transmission (depressed b-wave, normal c-wave) and retinal degeneration with marked synaptic and possible transsynaptic degeneration
